Nematode means invertebrate animals of the phylum nemathelminthes, and class nematoda, i.e., unsegmented round worms with elongated, fusiform, or saclike bodies covered with cuticle, and inhabiting soil, water, plants, or plant parts, may also be called nemas or eelworms.
Plastic means material which contains as an essential ingredient a high polymer, such as polyethylene terephthalate, high density polyethylene, Vinyl, low density polyethylene, polypropylene, polystyrene resins, multi-materials like acrylonitrile butadiene styrene, polyphenylene oxide, polycarbonate, polybutylene terephthalate ;
Plastics means synthetic materials chemically formed by the polymerization of organic (carbon-based) substances. Plastics are usually compounded with modifiers, extenders, and/or reinforcers and are capable of being molded, extruded, cast into various shapes and films or drawn into filaments.
Tube means an x-ray tube, unless otherwise specified.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
coronavirus means severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2);
Epinephrine auto-injector means a device for immediate self-administration or administration by another trained person of a measured dose of epinephrine to a person at risk of anaphylaxis.
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
Powertrain means the total combination in a vehicle of propulsion energy storage system(s), propulsion energy converter(s) and the drivetrain(s) providing the mechanical energy at the wheels for the purpose of vehicle propulsion, plus peripheral devices.
Polymer means a substance consisting of molecules characterised by the sequence of one or more types of monomer units. Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. A polymer comprises the following:
Pyrolysis means the thermal degradation of a substance in the absence of any oxidising agent, which does not form part of the substance itself, to produce char and gas and/or liquid; and
SOFRi means the SOFR for:
Metal means precious metal, including, without limitation, gold, silver, platinum, palladium, rhodium, iridium, and ruthenium.
thalassemia means a group of inherited disorders characterised by reduced or absent amounts of haemoglobin.
Polyolefin adhesive means an aerosol adhesive designed to bond polyolefins to substrates.
Dyslexia means a disorder of constitutional origin manifested by a difficulty in learning to read, write, or spell, despite conventional instruction, adequate intelligence, and sociocultural opportunity.
Pistol means any firearm with a barrel less than sixteen inches in length, or is designed to be held and fired by the use of a single hand.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Brachytherapy means a method of radiation therapy in which sealed sources are utilized to deliver a radiation dose at a distance of up to a few centimeters, by surface, intracavitary, or interstitial application.
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one micrometer is rejected by an engineered barrier, primarily through a size exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Cell means a single encased electrochemical unit containing one positive and one negative electrode which exhibits a voltage differential across its two terminals.
